Stable Positron Acceleration in Thin, Warm, Hollow Plasma Channels
T. Silva, L. D. Amorim, M. C. Downer +4
Hollow plasma channels are attractive for lepton acceleration because they provide intrinsic emittance preservation regimes. However, beam breakup instabilities dominate the dynami…
Analytical Solution to Electron Beam Envelope Evolution in a Plasma Wakefield
J. Yan, A. Farrell, L. D. Amorim +1
Beam-induced ionization injection (B-III) is currently being explored as a method for injecting an electron beam with a controlled density profile into a plasma wakefield accelerat…
Porting WarpX to GPU-accelerated platforms
A. Myers, A. Almgren, L. D. Amorim +20
WarpX is a general purpose electromagnetic particle-in-cell code that was originally designed to run on many-core CPU architectures. We describe the strategy followed to allow Warp…
AWAKE, The Advanced Proton Driven Plasma Wakefield Acceleration Experiment at CERN
E. Gschwendtner, E. Adli, L. Amorim +88
The Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) aims at studying plasma wakefield generation and electron acceleration driven by proton bunches. It is a…
Self-modulation instability of ultra-relativistic particle bunches with finite rise times
J. Vieira, L. D. Amorim, Y. Fang +3
We study the evolution of the self-modulation instability using bunches with finite rise times. Using particle-in-cell simulations we show that unlike long bunches with sharp rise…
Electron trapping and acceleration by the plasma wakefield of a self-modulating proton beam
K. V. Lotov, A. P. Sosedkin, A. V. Petrenko +6
It is shown that co-linear injection of electrons or positrons into the wakefield of the self-modulating particle beam is possible and ensures high energy gain. The witness beam mu…
